Leo, it is extremely interesting and I often do not know the answer to the questions that there are but that means I can go and research the answers and carry out experiments to try to understand. I’m not working y myself. There are colleagues and other team members and we bounce ideas off each other.
If it was easy, I think I would not still be doing it. However, I don’t describe it or think of it as hard. I think of it as challenging and engaging and it therefore keeps my interest.
